Nerds Unite: Prosthetics Inspired By Comics And Beyond!

March 6, 2018 by Lara Grant 39 Comments

Open Bionics is a company creating prosthetics inspired by heroines, heroes and the fictional worlds they live in. The designs emblazoned on their first set of bionic hands include ones drawn from Queen Elsa from Disney’s Frozen, and Marvel’s Iron Man. The best thing about what they are doing is they offer you, dear reader, a chance to lend your own super powers of design and engineering. Open Bionics offers up 3D print files for several hand designs, hardware schematics and design files for their controller boards, firmware, and software to control the robotic hands with. Other than their website, you can also find all of the files and more on their GitHub account. If you’d like to devote a good amount of time and become a developer, they have a form to contact them through. To help with sourcing parts for your own build, they sell cables for tendons, muscle sensors, and fingertip grips in their online store.

We first came to learn about this company through a tipster [Dj Biohazard] who pointed to a post about their partnership with an 11-year-old Tilly, who is pictured on the left. Her bionic hand is an Open Bionics prototype whose design is based on the video game, Deus Ex. The best way products like these are improved are through the open source community and people like her.

Specific improvements Open Bionics state on their website are:

The customised bionic arms are manufactured in under 24 hours and the revolutionary socket adjusts as the child grows.
The bionic arms are light and small enough for those as young as eight.
The bionic arms use myoelectric skin sensors to detect the user’s muscle movements, which can be used to control the hand and open and close the fingers.

Read more about Tilly’s story and her partnership with Open Bionic’s on Womanthology. Tilly seems to have a dream of her own to “make prosthetics a high fashion piece – something that amputees can be proud to wear.”

We at Hackaday have written about several open source prosthetic developments such as a five-day event S.T.E.A.M. Fabrikarium program taking place at Maker’s Asylum in Mumbai and the work of [Nicholas Huchet]. What superhuman inspired designs would you create?

[Marla]’s New Arm

January 19, 2017 by Jenny List 32 Comments

It is especially rare to see coverage in the mainstream media that involves a hackspace, so it was a pleasant surprise yesterday when the local TV news where this is being written covered a story that not only highlighted a hackspace’s work, but did so in a very positive light.

[Marla Trigwell] is a young girl from Newbury, UK, who was born without a left hand. She had been provided with prosthetics, but they aren’t cheap, and as a growing child she quickly left them behind. Her parents researched the problem as modern parents do, and found out about recent advances in 3D-printed prosthetics lowering the bar to access for those like [Marla] born without a limb. Last month [Marla] received her new 3D-printed arm, and she did so courtesy of the work of [Andrew Lindsay] at Newbury and District Hackspace.

The arm itself is a Team Unlimbited arm version 2.0 Alfie edition, which can be found on Thingiverse with full sizing instructions for adjusting to the recipient in Customizer. As the video below the break shows, [Marla] appears very pleased with it, and is soon mastering its ability to grip objects.

This story is a fantastic demonstration of the ability of a hackspace to be a force for good, a true community organisation. We applaud [Andrew], NADHack, and all involved with it for their work, and hope that 3D printed arms will keep [Marla] with a constant supply of comfortable and affordable prosthetics as she grows up.

Hackaday Prize Entry: Raimi’s Bionic Arm

May 8, 2016 by Moritz Walter 9 Comments

Sometimes, the most amazing teams make the most wonderful things happen, and yet, there is just not enough time to finish all the features before the product ships. This is what happened to Raimi, who came to this world missing a right hand and half of her right forearm. Raimi is now 9 years old, and commercial mechatronic prostheses are still only available to those who can afford them. When Raimi’s father approached [Patrick Joyce] to ask him for help in building an affordable prosthesis, he knew it would matter, and went right to work.

3D Printing Goes Hand In Hand With Iron Man Inspired Prosthetic

October 17, 2014 by Sarah Petkus 10 Comments

It’s exciting how much 3D printing has enabled us to produce pretty much any shape for any purpose on the fly. Among the most thoughtful uses for the technology that we’ve seen are the many functioning and often beautiful prosthetics that not only succeed in restoring the use of a limb, but also deliver an air of style and self-expression to the wearer. The immediate nature of the technology allows for models to be designed and produced rapidly at a low-cost, which works excellently for growing children. [Pat Starace’s] Iron Man inspired 3D printed hand and forearm are a perfect example of such personality and expert engineering… with an added dash of hacker flair.

With over twenty years of experience in animatronics behind him, [Starace] expertly concealed all of the mechanical ligaments within the design of his arm, producing a streamline limb with all the nuance of lifelike gesture. It was important that the piece not only work, but give the wearer that appropriate super hero-like feeling while wearing it. He achieves this with all the bells and whistles hidden within the negative space of the forearm, which give the wearer an armory of tricks up their sleeve. Concealed in the plating, [Starace] uses an Arduino and accelerometer to animate different sets of LEDs as triggered by the hand’s position coupled with specific voice commands. Depending on what angle the wrist is bent at, the fingers will either curl into a fist and reveal hidden ‘lasers’ on the back of the hand, or spread open around a pulsing circle of light on the palm when thrust outward.

The project took [Starace] quite a bit of time to print all the individual parts; around two days worth of time. This however is still considered quick in comparison to the custom outfitting and production of traditional prosthetics… not to mention, the traditional stuff wouldn’t have LEDs. This piece has a noble cause, and is an exciting example of how 3D printing is adding a level of heroism to everyday life.

Thank you Julius for pointing out this awesome project to us!
